It will thus be seen that the rear end part of the frame 46 is Wedge shaped.

The rear surface of the piece 45 is ground, and will readily receive the marks Al (Fig.2) of an ordinary pencil or other convenient Writing means; and the front surface 45 of this piece is also preferably ground or frosted, to `diffuse the light in its passage to the sensitized surface,

On the fiat upper end of the camera is the receptacle 48 for the frame 46, having its open front end set back from the front side of the camerak so that the finger pieces 47 of the frame. 46 may project therefrom Witlr out projecting past the front side of the camera.; and having on its rear end a small door 49 rhinged along its top and `having a spring 49 that Will hold thedoor closed or yhold 1t raised for access to the rear surface 45r of the piece 45,`When the frame 46 is held in the receptacle 48.` This frame 46 is thus suitable springlatch 50 that lies in a recess v51 pressed Lin Ithetop and front` up'- per corner of the shell 4at the. middleithere of," Thus, theV inscription -`inayfbe made on theyfrear surface of the piece 45 While it is co`nvenient1y'held inthe camera, and With entire area` of the` vbla-ck` of the camera affording a rest for the handand arm. The Iframe 46 is then Withdrawn from the receptacle48 andv inverted, and then "inserted in th'eoperatingspace 2`8vinthe manner` above described, ,whereupon afn'egative copy of the inscription is recorded on the sensitized surfacefby the action of` the light shining through 'the transparent material around and past theV more opaque marksA of the inscription on said piece 45. f f l p n I insurefin ersion of the framel 46 'by beveling itssides`52 (Figs. l and 2) `and corres ondingly lieveling the inner sides of the holder 48 in one, direction, and the vsides 54 Y l straight; Vand the upright parts 26 extend up so asfa-rfas'ythe lower side kof the partition 6, to form liftedy rear ends for the' operating chamber at the` sides, Where not occupied by pece45A and' its frame 46, vvhen these ushedinto operating position. "Tt will derstood that the beveledsides 54 are be u' long enough, and the frame 46 fits them accurately enough, to insure proper guidance and steadiness of the frame while it is being insertedand after it is brought into operativeposition; causing the transparent piece 45 to come parallel with or squarely against the sensitized surface.

To properly prevent the entrance of light aro-und the outside of the frame 46, the lower' side of the partition 6, the top of the plate 40, and the sides 54 are preferably all covered with a soft cushioning material 56, such as soft leather; which thus forms a lining for the operating chamber 28 in its front part. This lining 56 continuesback across theledges 54 on rearl ends of the sides 54, and the ledge 44 in the raised part 44; and the upper surface of the shutter 39 also has a covering 57 formed of a continuation of the lining 56 on vthe plate 40. Thus, there are contacting surfaces of this soft material all around the `abutment of the shutter 39; This coveringfmaterialf entends do'ivn onto the inclinedfpar-t`42"o1f this platef40`; and at the top the material 56 is preferably lcontinued up intofthe off-set l0. Since the frame is Wedge-shapeduat top', bottom and sides on its rear end, it readily yenters-theop,l eratingchamber `betweenl the" linings `v56 thereof .Where they flare out froi'ny the chamberfat thelfront endy asjust described, and `Will' readily slide over the lining `57 onfthe top of the shutter 39;Ik

lnI the insertionof the operating` chamber 28, the shutteri); is of `,course pressed Wide openas soon' `as the rear end of the frame 46 has slightly passed the hinge ofr the shutter."l This, therefore, is some time before the"p'iece 45V hascon'ie into complete voperative position' in photographic proximity `with the' sensitized sur? face; and during the `interval from the fopen# ing oftheshutter until thiscomplete operatiife position has beenreached, there' `will, nevertheless, be" some 4 passage oflight tl'iroughthelpiece 45 tothe filing l find in practise, that' with the "piecef45` 4made of translucent material,l or rougliened or frost? ilo edfor otherwisetreated "to male"`ittrans` u lucent and reducefthe quantity of light 'pass ving through it to al proper"Clegi'ee,ancl"to 1nopcrly` difiuse this liglitgthereis no appieciable premature action onV the *sensitized surface; and, at thesaiiie time, the printing after the f complete operative position has been reached isffaccomplishedfin "a Vjconveii'- i :en'tly short time, ln addition to being'made translucent, thepiece 45 niay bevof a suitable colorto eliminate some ofthe light rays'l` I 6nd that"ordinaryl red glass operates'veify satisfactorily in this"y respect; and even blue glass is superior to White or clear glassl l To insure against thepassage of any light from" the operating chamber "to lthe Winding chamber 6`betWee`n the roller 35and`the`rear end of the partition o, a strip 58 of iieizihle iiiateiialu such as sott leather7 may he mounted on the upper side of the raised part #le part of said surface during said periods, hut the desired action of the light iiei'eoi While said inw r. is for a longer pebeaiing against the yoley 35, across che riodheldiii said photogijraghic proximity-to space between it anc. t" part on said wirt oi.' said. surface.
